JAMES A, .FEGNGFBRUKLYN YORK.

Leiters Patent No. 87,493., dated .March 2,' 1869.

` RQVED SPRIiTC-HBEI) BTTOM The icheluie :ofen-eri to in these Letters mutant and making part of tlm Bc it known that I, JAMES A. Ene-An, of Brooklyn, Kings, county, State of New York, have invented an improved Bed-Bottom, or Spring-Mnttress; and I do hereby declare the iollowing,description and eccoxnpnnying drawings are suiiieient to enable :my person skilled in the art or science to which it most nearly eppertains to make and use my said invention or improvements without further invention or experiment.

The nature of my invention and improvement in springbed bottoms consists in n hinge, made-oi' four metal` plntesunited by three joints,in combination with `the frames, springs, end strips, hereinafter described.

, In ,the following more exact description of iny inven tion, `I shall referto the accompanying drawings, form- 'lg part` of this specification- Figure .1 being a' plan, and l l Figure il', an' elevation. of one of my'iniproxfed bedbottoms. The bottom freine A supports the springs lB' B, which in turn support the top frame O.

Between thc top Vand bottom frames, et each end V and side ofthe bed-bottom, are placed hinges, D D,

consisting of four jnetnl pint-es, connected togetherby three l'linge-joints, the two intermediate pint-es being mede of the saine length, A

` The end plntesofench hinge nre to be irmlysecnred,

'one to the 'rail of the bottom frame, and the otherto the correspondingrail ofthe top frame, and are to be so placed that the axes ofthe joints, or hinges, et the ends of these plates., shall be equnlly distant vfrom cor# responding ends of their respective rails, and at right `nngiles to the direction-of the length ofthe rail.

These hinges ere to be made wide enough and strong enoughV to prevent 'their bending or springing Vto any considerable extent edgewise, and lateral motion, either of the sdeor end rails-of the top frame, is thus prevented, and the top frame keptdreetly over the bottom one, while itis allowed tovibrate np and down freely.

To keep in piece the tops ofthe springs, and form n suitable beni-ing for the bedding, I fasten, u'pori the frame G, strips rof sheetmetal,-E E, and connect them to the adjoining springs', Joy passing them around th wire'of the spring and riveting them, or in some other' suitable manner, :md connect the top of each spring .to the tops' of the elija-cent springs by similar strips,-

F F, attaching them'to the.A springs in a, similar mamner.V The elongation -of the tops of the springs will,

particular part t-o ,sink when pressed. l

What i claim as my-invention, nnd Adesire 'to secure by Letters Patent, is'- in eii'eoi, lengthen these connections, and'allow any A liingqninde of four metal plntesunited by three nnd'striiis E E, substantially ais described. JAMES A.
